sure into the tank of the carbonator. Ar- It is impracticalto so regulate 'tlIBlflOW'Of ranged in the tank of the carbonator is the gas from i'fiask9zto the carbonator .5 that all usual float -F which operates a switch of the gas will be taken in solution withthe S to control the operation of motor waterin'ithe carbonator. Accordingly, some M and pump P-. When the float of :the gas necessarily passes from thecar- 50 F lowers,the motor circuit will be closed bonatorzto the tanklt along with the water and accumulates in the top of tank 14. After tank 14 is repeatedly filled with carbonated water, the pressure of the accumulated gas therein becomes equal to the pressure in the 5 carbonator. When this occurs, the pressure in the carbonator will not force carbonated water from the carbonator into the tank 14, and the pump -P is therefore required for this purpose. However, the pressure in 10 tank 14 would ordinarily eventually rise beyond the power of pump P' and render such pump inoperative for this purpose. Accordingly, the pipe 15 is provided so that as the water rises in tank 14 the gas in the top of the latter is not compressed but is displaced through said pipe 15 back into the carbonator. In this way, the pressure in the tank 14 and in the carbonator 5 is equalized so that the pump P may always operate to force the carbonated water into the tank 14. The check valve 15a or its equivalent is a very important part of the present apparatus because it prevents the gas from flowing through pipe 15 from the carbonator to the tank 14. Assuming that the tank 14 is filled and that the pressure in such tank and in the carbonator is the same, the pressure in tank 14 will be reduced with.- out reducing the pressure in the carbonator when water is drawn oil from the tank 14 through outlet pipe 16. As soon as the pressure in tank 14 becomes lower than that in the carbonator, the pressure in the carbonator will force carbonated water from said carbonator through the non-positive pump -P' even if the latter is not operating at this particular time. This results in lowering the level of the carbonated water in the carbonator 5 so that float F lowers and closes switch S, thereby throwing pumps 'P and -P into operation for carbonating more water in carbonator 5 and forcing more carbonated water into tank 14 as it is drawn 0H from the latter. Should tank 14 fill with carbonated water up to the level of pipe 15, the carbonated water may return to the carbonator 5 through pipe 15, and then pass back to pump -P-. This circulation of the carbonated water will permit the same to properly accumulate in the carbonator for raising the float F to operate switch S and throw the pumps P and P- out of operation at the correct time. If desired, the pipe 15 may be extended into the carbonated water tank of the carbonator so as to open therein below the level of the carbonated water, as shown by dotted lines at 15. This will prevent free flow of gas from the carbonator to the storage tank 14 through pipe 15, so that the checkvalve 15a might be omitted.

What I claim is: V

1. In a bath apparatus, the combination of a carbonator having a carbonated water tank and a motor-operatedpump for supplying said tank with water to be carbonated, said carbonator further having a float-operated switch for throwing the motor of the pump out of operation when the carbonated water rises to a predetermined level in said tank and for throwing said motor into operation when said carbonated water lowers to a predetermined lower level in said tank, a storage tank connected to said carbonator to re ceive carbonated water from the latter, a nonpositive pump for forcing the carbonated water from the carbonator to the storage tank, a motor for operating said non-positive pump operatively associated with said floatoperated switch so as to be thrown into and out of operation simultaneously with the motor of said water supply pump, and a gas bypass connection between the top of said storage tank and the top of the carbonator tank having a check valve therein to prevent flow" therethrough from the carbonator tank to the storage tank.

2. In a bath apparatus, the combination of a carbonator having a carbonated water tank and a motor-operated pump for supplying said tank with water to be carbonated, a storage tank connected to said carbonator to receive carbonated water from the latter, a further motor-operated pump for forcing the carbonated water from the carbonator to the storage tank a float-operated switch for simultaneously throwing both of said pumps into or out of operation, and a gas by-pass connection between the top of the storage tank and the carbonator tank.

In testimony whereof I afiix my signature.
